Hello, thanks for putting in your effort to create this incredible mod - it's literally something that I'd been wishing for in Minecraft for the longest time.

I just have an issue to report, pertaining to custom terrain. I attempted to load a world exported from WorldPainter (orginally a heightmap), but it acted strange. I should note that I did change the world to Custom Cubic with an online NBT editor (the Cubic Chunks plugin for WorldPainter does let you export as a cubic world, but not specifically the Custom Cubic world type). When in the world, however, the LOD did not work for the entirety of the exported terrain, only in pockets. The only way to get it to expand was to enter an unloaded (by the LOD) area and move around a lot, then a little bit more of it would load in that area.

(The flat appearance outside of the custom terrain is due to the fact that I changed the settings of the Custom Cubic world generation in the file.)

Eventually, I did find a solution, sort of. I simply used the CCPregen with either the Populate or Light chunk detail setting and it would appear in the LOD. Given that this takes additional time however, its not a perfect solution, although it is definitely serviceable (it doesn't take too long - definetely far faster then it was taking without it).

(I was using a different version of the WorldPainter imported map when I reached the solution, hence the different appearance.)

Just felt that you as the developer should know that custom terrain - at least when imported from WorldPainter - acts weird.

Also, when I looked through the old discussions in a search for an answer to this problem I also found this image, which seems to suggest that custom terrain did work, or there is a way to make it work?

Anyway, thank you for your work on this mod, it is truly incredible.

How long did it take to pregen all those chunks? what were the dimensions of the pregen? I'm trying to use ccpregen on a custom worldpainter world myself but I have no idea how the mod works and im not even sure it is doing anything. I am pregenerating a 4096x4096 area about 2000 blocks tall.

The flat appearance outside of the custom terrain is due to the fact that I changed the settings of the Custom Cubic world generation in the file.

this could very well be caused by some kind of floating-point error in the CubicWorldGen rough generator code, caused by the fact that the world is perfectly flat (which is an edge case i don't think i ever took into account). could you send me the exact preset you used to create this world?
